Cranking mechanism

Abstract

A cranking mechanism preferably includes a crank shaft, a one way bearing, a clutch, a reel shaft, a driven gear and at least one reel. The clutch preferably includes a clutch housing, a clutch pack and a pressure washer. The clutch housing includes a clutch pack housing and a drive gear. The one way bearing and the clutch are retained on the crank shaft. A hand knob is threaded on to a threaded end of the crank shaft to exert pressure on the clutch pack. The driven gear is pressed on to the reel shaft. The at least one reel is retained on at least one end of the reel shaft. The hand knob is tightened against the clutch pack to frictionally engage the crank shaft with the drive gear. The drive gear rotates the at least one reel.

 a reel shaft; 
 a driven gear is retained on said reel shaft; and 
 at least one reel is retained on at least one end of said reel shaft, wherein rotation of said tightening device causes said clutch to have engagement with said crank shaft, rotation of said crank shaft rotates said at least one reel. 
 
     
     
       9. The cranking mechanism of  claim 8 , further comprising:
 said clutch includes a clutch housing and a clutch pack, said clutch housing includes a clutch pack housing and a drive gear, a clutch cavity is formed in one end of said clutch pack housing, said drive gear extends from an opposing end of said clutch pack housing, said clutch pack is retained in said clutch cavity. 
 
     
     
       10. The cranking mechanism of  claim 9 , further comprising:
 a pressure washer is located between said tightening device and said clutch pack. 
 
     
     
       11. The cranking mechanism of  claim 9 , further comprising:
 a clutch bearing is retained on an outside diameter of said clutch housing, said clutch bearing is retained in a retention structure. 
 
     
     
       12. The cranking mechanism of  claim 8 , further comprising:
 a thrust bearing is located between said drive gear and said one way bearing. 
 
     
     
       13. The cranking mechanism of  claim 12 , further comprising:
 a thrust washer is located between said thrust bearing and said drive gear. 
 
     
     
       14. The cranking mechanism of  claim 8 , further comprising:
 a controlled release of a bow string from a drawn position to a rest position is implemented by loosening said tightening device, which disengages said crank shaft from said drive gear. 
 
     
     
       15. A cranking mechanism comprising:
 a crank shaft; 
 a one way bearing is retained on one end of said crank shaft;
